(1) Disinfection treatment. It mainly kills germs or viruses attached to the surface of the seeds or even inside, and there are two methods of scalding and chemical treatment.
1 warm soup seeds. First, the seeds should be stained. In a clean container, clean the water, soak the seeds, simmer, remove the mites, remove the impurities, and then put them in warm water to make the seeds swell and swell, so that the pathogens start to sprout. It is easy to be burned to death in the next step. After 3 to 4 hours of staining, put it in hot water with a constant temperature of 50-55 °C for about 5 to 10 minutes, then take it out and cool it in cold water to germination.
2 trisodium phosphate stains. After 3 to 4 hours of clear water soaking, put it into 10% trisodium phosphate solution (50 g of trisodium phosphate and dissolve it into 500 g of water) for 20 minutes, remove it and wash it with water, then germination.
(2) Seeds and germination. After the disinfected seeds are stained for 6-8 hours, they are taken out and washed. The treated tomato seeds are wrapped in a wet towel, germinated at 25-30 ° C, and rinsed with water 1 or 2 times a day.
